Questions and Answers

A quick reference for common questions about HealthyPi Move. For walkthroughs, see Getting Started.

Before you buy

Where can I buy a HealthyPi Move?
Through Crowd Supply.

Is the mobile app available on iOS?
Yes. The HealthyPi Move app is in both the App Store and Google Play. See Getting Started → Install the mobile app.

Is HealthyPi Move waterproof?
No. Don’t immerse it in water or wear it in the shower.

Is HealthyPi Move a medical device?
No. It’s a research and wellness platform, not certified for diagnosis or treatment of any medical condition.

Setting up your Move

I just got my device — where do I start?
Follow Getting Started from the top. It walks through charging, pairing, and your first sync.

How do I update the firmware?
Recommended method: Update using nRF Connect. The unit ships with pre-release firmware and should be updated before regular use.

Will my ECG recordings and settings survive a firmware update?
Yes. Stored recordings, time, and other settings are preserved across firmware updates.

Daily use

How do I change the time zone on the watch?
Set the time zone on your phone first, then open the HealthyPi Move app → Devices tab → Set Time. The watch picks up the phone’s current time zone.

How do I view the ECG recordings I’ve taken?
Open the app → Devices tab → Fetch Logs → connect to your Move. All recordings will appear in the list.

Can Move stream wrist PPG and finger PPG at the same time?
No. The two PPG paths use the same processing pipeline, so only one can stream at a time.

Where are the safety and regulatory documents?
On the Regulatory Info page (Safety instructions, UK Declaration of Conformity, CE Declaration of Conformity).

Health metrics

What’s a normal resting heart rate?
For most adults, 60–100 bpm. Lower resting heart rates (e.g. trained athletes at 40–60 bpm) typically indicate stronger cardiovascular fitness.

What’s a normal SpO₂ level?
Generally 95–100 %. Persistent readings below 90 % warrant a conversation with a healthcare provider.

Firmware & development

I get an error like application/app path is not valid when building.
The target board needs to be set explicitly to healthypi_move/nrf5340/cpuapp. See Get the Move Firmware for the full setup.

Where’s the firmware source?
github.com/Protocentral/healthypi-move-fw. Hardware design files are at github.com/Protocentral/healthypi-move-hw.

Troubleshooting

The device has stopped advertising — my phone can’t find it.
Press and hold the side button for 1–2 seconds. The watch will restart and re-advertise.

The firmware update keeps failing.
Restart the device (hold the side button for 1–2 seconds), then try again. If multiple attempts fail with the nRF Connect app, try nRF Connect Device Manager instead.
